The Guru of 3D posted a review on the Dark Power Pro 600 Watt PSU

Face it, high-end gamers PCs these days need a good power supply unit (PSU). The power consumption that a PC can create these days is a little unheard of. Increased transistor counts for processors (GPU/CPU) versus higher clock frequencies and most of all do not ignore the "Dual & Quad" trend. We have multi-core CPUs, and instead of one graphics cards we now have the option to double up graphics power with cards in SLI or Crossfire mode.

And with such factors in mind we land at a product line called BeQuiet! "Dark power Pro". The Dark Power Pro is a 600 Watt PSU which places it in the high-end segment. A PSU which (although not certified) is ready for SLI and Crossfire as it has dual 12 volts rails with 20 AMPs each, active PFC and smart fan technology.
